Endoscope with function of acoustic wave detection and voiceprint comparison

Abstract

The present invention provides an endoscope with function of acoustic wave detection and voiceprint comparison. The endoscope includes a flexible tube, a hand-held host and a sound receiving element. The hand-held host includes an analog-to-digital converter, a storage unit and a digital signal processor. The sound receiving element is disposed at the control module. The sound receiving element is used to convert surrounding acoustic waves to acoustic analog signals, and transmits the acoustic analog signals to the analog-to-digital converter of the hand-held host via the signal wires. The analog-to-digital converter converts the acoustic analog signals to digital signals, and transmits the digital signals to the digital signal processor for comparing the digital signals with the voiceprint data stored in the storage unit. The digital signal processor makes the comparison result shown at the display of the hand-held host.

1 . An endoscope with function of acoustic wave detection and voiceprint comparison, comprising:
 a flexible tube, one end of the flexible tube having a control module, and a plurality of signal wires are disposed in the flexible tube;   a hand-held host, comprising an analog-to-digital converter, a storage unit and a digital signal processor, and a plurality of voiceprint data are stored in the storage unit; and   a sound receiving element, disposed at the control module to convert surrounding acoustic waves to acoustic analog signals, and transmitting the acoustic analog signals to the hand-held host via the signal wires;   wherein, when the acoustic analog signals are transmitted to the hand-held host, the analog-to-digital converter converting the acoustic analog signals to digital signals and transmitting the digital signals to the digital signal processor for comparing the digital signals with the voiceprint data stored in the storage unit.   
     
     
         2 . The endoscope according to  claim 1 , wherein the control module further comprises an image-capturing element and a plurality of light-emitting elements, and image data and control signals from the image-capturing element are transmitted by the signal wires. 
     
     
         3 . The endoscope according to  claim 2 , wherein the light-emitting element is light-emitting diode (LED). 
     
     
         4 . The endoscope according to  claim 2 , wherein the image-capturing element is a sensor of CCD or CMOS corresponding to optics lens for getting the image data. 
     
     
         5 . The endoscope according to  claim 1 , wherein the sound receiving element is a microphone. 
     
     
         6 . The endoscope according to  claim 5 , wherein the microphone is an omnidirectional microphone or a cardioid microphone. 
     
     
         7 . The endoscope according to  claim 1 , wherein the hand-held host further comprising a display, buttons, two communication interface ports, and a memory slot. 
     
     
         8 . The endoscope according to  claim 7 , wherein the display showing a comparison result from comparing the digital signals with the voiceprint data stored in the storage unit by the digital signal processor. 
     
     
         9 . The endoscope according to  claim 1 , wherein the hand-held host further comprising a speaker to broadcast the acoustic analog signals.
